HENRY BECKER, OF EAST COCALICO TOWNSHIP, PENNSYLVANIA. Letters Patent No. 87,949, dated March 16, 1869.

To all whom it may. concem 'Beit known that we, J soon Lu'rz, J OHNA. EBERLY,

and HENRY Bncxmtof East Oocalico township, in

the county of Lancaster, and, State of Pennsylvania, have invented-a new and useful Improvement on the old-fashioned Threshing-Machines; and we do hereby declare that the following is a full, clear, and'ex'act description of the. construction and operation of the same, reference being had to the accompanying drawings, making a part of this specification, in .which Eigure 1 is a perspective view of the machine, with our improvements in place.

Figure 2, a side elevation, or plan view.

Figure 3, the same, as seen from the rear.

The nature of our invention consists. in the manner of arranging the gear, in reference to the use of two spiked cylinders, salts on a small use of concaves.

To enable others skilled in the art to make and use to say that we use F G, the upper, F, or greater in diameter than the G, and has six rows of spikes, or heaters. cylinder G'has fifteen rows of spikes, but on the shaft of the upper, there is a pinion, B, of, say, seven cogs, on the one end, and a strap-pulley, D, on the other end of this shaft.

The lower cylinder, G, shaft has a large spur, or cogged wheel, A, with about forty-two cogs, and a strap-pulley, O, on the one side, and also a strap, or belt, or connecting-pulley, the shaft.

The arrangement of this gear and cylinders is clearly shown, as also the sides I, top, or cap H, and framesupports K K, and the feed-board, or inclined plane M, and discharge-table, or plate N.

soas to produce the most happy reand compact machine, without the two cylinders, one over the other, being somewhat larger, lower one,

E, on the opposite end of 4 by means of less power than The operation is'such, that by the less rows of spikes and increased speed of the upper, and larger cylinder, making six revolutions to the one of the lower, this lower being provided with fifteen rows of spikes, so placed, that while they come closely to each other, they do not interfere with each other, the upper and lower cylinders'jointly drawing the straw and grain inward, and'work it out over' the discharge-table N, in a rapid manner, while every grain .isthoroughlybeaten out, when but one cylinder is used, combined with the ordinary coucaves, or when a large spur-wheel is employed on the side to mesh into pinions on each shaft of the cylinder, of uniform size and rows of spikes, such, for instance, as that of ErD. Street, rejected 1861, and other attempts heretofore made to utilize two cylinders.

A fair trial, by competentjudges, assures-us that the arrangement of the gearing and cylinders, as herein presented, results in producing'such a machine that will meet the approbation of farmers generally as a compact, eflicient, and desirable machine, requiring but little power.

We are aware, that separately considered, there is no novelty in any"- of its parts, but collectively, as a whole, it is both novel and truly useful. Therefore,

What we claim as our invention, is

The construction and arrangement of a threshinginachine, when made with cylinders F G, the one with its pinion B, and theother with its spur wheel A, in cqrhbination with the pulleys O D E, all arranged and operating in the manner and for the purpose specified.
